Solution Overview

Problem

Current methods for improving the proliferative ability of mesenchymal stem cells in vitro are limited by the complexity of maintaining optimal environmental conditions and the low proliferative capability of somatic cells, necessitating a more effective approach to select and enhance stem cells with high proliferative potential.

Innovation Solution

A marker detection composition and method utilizing the DANCE gene expression level to assess and enhance the proliferative ability of stem cells, involving the measurement of DANCE gene or protein expression levels using mRNA or protein analysis techniques, and administering DANCE protein or gene to improve stem cell culture conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If mesenchymal stem cells are cultured in vitro to improve proliferative ability, then cell proliferation can be enhanced, but environmental conditions must be precisely controlled which increases system complexity

Engineering Contradiction:
Improveproliferative abilityVSAvoidenvironmental control complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent changes the biochemical parameter of the culture medium by adding specific growth factors (EGF at 20 ng/mL, FGF-basic at 20 ng/mL, IGF-1 at 20 ng/mL) to optimize cell proliferation. This approach enhances proliferative ability through controlled parameter adjustment rather than complex environmental control systems.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If somatic cells are used for cell therapy, then ethical problems are avoided, but proliferative capability is low which limits practical application

Engineering Contradiction:
Improveethical acceptabilityVSAvoidproliferative capability
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies parameter changes by introducing specific growth factors into the culture medium to enhance the proliferative capability of somatic cells (mesenchymal stem cells). This allows somatic cells to achieve higher proliferation rates while maintaining their ethical advantages, resolving the contradiction between ethical acceptability and proliferative capability.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If embryo-derived pluripotent stem cells are used, then high proliferative ability is achieved, but ethical problems and genetic instability arise

Engineering Contradiction:
Improveproliferative abilityVSAvoidgenetic stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Instead of using embryo-derived cells to achieve high proliferation, the patent inverts the approach by enhancing the proliferation of adult somatic cells (mesenchymal stem cells) through growth factor supplementation. This reversal allows achieving high proliferative ability while maintaining genetic stability and avoiding ethical issues associated with embryonic cells.

Inventive Principle:
Principle #13The other way round (Inversion)

4Stability of the object's composition

If in vitro culture conditions are optimized for mesenchymal stem cells, then proliferative properties are maintained, but the complexity of adjusting nutrients, pH, temperature, and osmotic pressure increases

Engineering Contradiction:
Improveproliferative propertiesVSAvoidculture condition complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent simplifies the complex environmental control by focusing on changing the biochemical composition parameter - specifically adding defined concentrations of growth factors (EGF, FGF-basic, IGF-1) to the culture medium. This approach maintains proliferative properties while reducing the complexity of controlling multiple physical parameters like pH, temperature, and osmotic pressure.

Inventive Principle:
Principle #35Parameter changes
